The structure of a randomly-formed flake-type wood composite mat is further defined and characterized. A model for the prediction of horizontal mass density distribution in a random flake mat is presented through application of two-dimensional random field theory. This model predicts the small-scale

โฆ Synopsis
A mathematical model for describing the structure of a randomly formed flake layer network is presented. The structural properties of the flake network are random variables in essence characterized by Poisson and exponential distributions. The model predicts distribution of: flake centres, flake area coverage, free flake length, and void size over the flake layer network. A computer program for simulating the random flake network and rapidly evaluating structural properties is developed as well. In addition, the structural properties of hand-formed flake layers are experimentally measured. Close agreement is found between mathematical model prediction, computer simulation and experimental measurements.

A rationale is presented for developing a mathematical model which describes a randomly packed, short-fibre-type wood composite. The model will utilize probability theory to insure random packing both in terms of flake position and orientation. Knowledge about the spatial relationship between wood e
## Abstract Titanium carbide (TiC)/polyethylene (PE) composites have been prepared with various volume fractions of TiC by a melt bleeding method. Two types of TiC powder with their different particle diameters, 1.48 ยตm (TiCโA) and ca. 100 ยตm (TiCโB), were utilized in the present study. The electri
